TYPO3 Core

I can confirm this issue being related to IE7 and TYPO3 4.4 with rtehtmlarea 2.0.5, having a site with about a thousand page. Just like Veronica said in her previous post, switching to the text panel which contains the RTE, IE7 just waits for 20-30 seconds.

We disabled script compression in the extension options, we added some apache directives to improve the backend responsiveness a little (see below) but the RTE still takes way too much time to load with IE7.

I've read a few topics here and there reporting slow behavior of the RTE with IE7 and TYPO3 4.4, but unfortunately, no solutions so far.

With IE8, it takes 5-6 seconds to switch to the text tab.

Being stuck with company policies, having the user switch from IE7 to IE8 isn't a likely solution for now, and many «usability improvements» in TYPO3 4.5 back-end seems a daunting change for many users.

Here's the apache directive we've used, basicaly, it saves a few seconds from downloading again and again all the static files used in the back-end.

even though 4.5 IMO still supports this browser, no change will be expected. therefore I am closing this issue.
